The Complete Guide to Healthier Animals and Higher Farm Productivity
If you raise pigs, cattle, chickens, or other livestock, you know the daily struggles. Diseases spread fast in crowded barns. The smell of ammonia burns animals’ lungs and brings complaints from neighbors. Bacteria hide in water lines no matter how often you clean. And mold in stored feed can make animals sick and hurt your profits.
Traditional solutions only go so far. Chemical cleaners miss spots and leave residues. Fans and ventilation can’t fix ammonia once it’s in the air. Chlorine in water loses power against the slime layer called biofilm that coats pipes.
Ozone technology offers something different. It’s been used in Europe for years to treat drinking water. Now farmers across North America are using it to tackle multiple problems at once. Ozone kills germs in the air and on surfaces. It destroys odor molecules instead of just covering them up. It cleans water lines and kills bacteria without chemicals. And it even helps keep feed fresh longer.
This guide covers how ozone works on real farms, what problems it solves, how much ozone systems cost, and how you can contact our team to discuss your operation.
Common Problems Ozone Solves in Livestock and Poultry Farming
Before we talk about solutions, let’s look at the everyday headaches that cost farmers time and money.
Disease Spread in Confined Barns
When you pack animals together, germs travel fast. Bacteria and viruses move through the air. They land on walls, feeders, and equipment. Workers carry them on boots and clothes from one barn to another.
In poultry houses, diseases like Salmonella and Campylobacter can wipe out entire flocks. In pig barns, respiratory diseases spread through contaminated air. In dairy operations, mastitis pathogens travel via shared equipment and water.
Standard cleaning has limits. Spraying chemicals misses the tops of rafters and the backs of fans. Fogging adds moisture, which can actually make breathing problems worse. And chemical residues mean you have to wait before bringing new animals in.
Ozone gas reaches where sprays can’t. It circulates with the air, getting into every crack and corner. And because it turns back into oxygen, there’s nothing to rinse away
Ammonia and Smell Problems
Animal waste breaks down and releases gases. Ammonia is the worst one. It’s heavier than air, so it settles down where animals breathe. Even low levels damage lungs and make animals more likely to get sick.
According to research from Iowa State University, ammonia in livestock barns often tops 8 parts per million. That’s way above the 1 ppm limit some places set for emissions. High ammonia levels in chicken houses can cause respiratory distress and reduce egg production. Ammonia control in pig barns is essential for growth rates and feed efficiency.
The smell also causes trouble with neighbors. Complaints can bring inspectors and even lawsuits. Some farmers have had to cut back herds because of odor issues.
See how our ozone odor control systems help farms stay on good terms with neighbors.
Dirty Water Lines
Here’s something many farmers don’t realize. Even if your water comes in clean, it can pick up bacteria inside your own pipes. A slimy layer called biofilm builds up inside water lines. This biofilm protects harmful bugs like E. coli and Salmonella. They hide in there and keep getting into your animals’ water no matter how much you flush.
Eliminating biofilm in livestock water lines is one of the biggest challenges in modern farming. Ozone is one of the few treatments that actually removes biofilm instead of just temporarily suppressing it.
Moldy Feed
Stored feed can grow mold, especially in humid weather. Molds make toxins called mycotoxins. These poisons weaken animals’ immune systems. They also lower feed conversion—meaning you need more feed to get the same growth. In dairy cows and laying hens, mycotoxins can get into milk and eggs, which creates food safety risks.
Mycotoxin mitigation in animal feed is a growing concern worldwide.
Manure and Wastewater
Handling manure is never fun. But it gets worse when wastewater sits untreated. High levels of ammonia and other pollutants can contaminate soil and water when you spread it on fields. Environmental rules keep getting stricter, and violations cost big money.
Livestock wastewater treatment solutions are becoming essential for larger operations. Ozone can help reduce COD in manure wastewater before storage or land application.
What Is Ozone and How Does It Work on Farms?
Ozone is just a special form of oxygen. Normal oxygen we breathe has two atoms stuck together—that’s O₂. Ozone has three atoms—O₃. That third atom wants to break off and grab onto other stuff. When it does, it burns up bacteria, viruses, and smell molecules.
Think of it like this. Chlorine works by poisoning germs. Ozone works by burning them up physically. There’s no poison left behind. After ozone does its job, it turns back into plain oxygen.
| Treatment Method | How It Works | Residue | Effectiveness Against Biofilm | Safety Concerns |
| Ozone | Oxidation | None (turns to oxygen) | Excellent | Moderate (requires monitoring) |
| Chlorine | Poisoning | Chemical residue | Poor | Chemical handling risks |
| UV Light | Radiation | None | Poor (line-of-sight only) | None |
| Hydrogen Peroxide | Oxidation | Water + oxygen | Good | Skin irritation |
| Formaldehyde | Poisoning | Toxic residue | Good | Carcinogen |

On farms, we use ozone two main ways:
- As a gas in the air to kill germs and stop smells
- Mixed into water to clean drinking lines and sanitize
Air and Surface Treatment with Ozone
Killing Germs in Barn Air
Ozone gas pumped into barns kills bacteria, viruses, and mold floating in the air and sitting on surfaces. It works better than you might think.
Research on hatcheries shows ozone-based disinfection systems can kill 99.999% of Salmonella and Campylobacter. That’s as good as the formaldehyde treatment many hatcheries use, but without the cancer risks and chemical handling problems. Studies from the University of Arkansas confirm these findings.
The big advantage is reach. Ozone goes everywhere air goes. It gets up into ventilation ducts, behind equipment, and into cracks where liquid can’t reach.
For poultry barn air disinfection, ozone is particularly effective because it reaches the litter and wall surfaces where pathogens hide.
Healthier Animals from Cleaner Air
Cleaner air means healthier lungs. When ammonia levels drop, animals breathe easier. They spend less energy fighting off respiratory stress and more energy growing.
In those hatchery trials, chicks from eggs treated with ozone had only 1.2% death rate in the first week. Chicks from eggs treated the old way with formaldehyde had 3.4% death rate. That’s 65% fewer chicks dying right at the start.
For growing pigs and chickens, reducing airborne pathogens in livestock houses means fewer respiratory treatments and better weight gain.
Research on Nanobubble Ozone Spray
A 2024 study from Japan looked at using nanobubble ozonated water spray in weaning pig rooms. The results were promising.
After treatment, airborne bacteria levels dropped significantly:
- E. coli in the air decreased by 85.7%
- Staphylococcus aureus decreased by 69.5%
The study also found that aerosol particle concentrations went down, meaning cleaner air for pigs to breathe.
For swine operations, this means fewer respiratory issues and better growth rates during the critical weaning phase. Contact us to learn more about air treatment options for your farm.

Ozone Water Treatment for Livestock
Cleaning Drinking Water
Ozonated water kills bacteria in drinking water. More importantly, it removes biofilm from pipes. Biofilm acts like a fortress for bacteria. Once it forms, germs hide inside and keep coming back no matter how much you treat the incoming water.
Ozone breaks down the slime that holds biofilm together. Without that protection, bacteria die off and stop re-contaminating the water.
Ozone water treatment for pig farms has shown remarkable results in reducing scours and improving feed conversion. For poultry operations, clean water means better hydration and fewer digestive issues.
A US patent for poultry drinking water systems describes using ozone as the main sanitizer, with copper materials providing backup protection when water isn’t flowing. This keeps water clean 24/7, even when birds drink less at night.
Two Ways to Get Ozone into Water
Most farms use one of two setups:
Venturi injection (like the XINOZONE X-TWO model) uses water pressure to pull ozone gas into the pipe. It works best where water flows steady most of the time. Learn more about how venturi injection works.
Ozonated water units hook right into your water line and make treated water as you need them. These are simpler to run and work well when water use goes up and down through the day.
| Method | Best For | Installation | Maintenance |
| Venturi Injection | Continuous flow, main water lines | Moderate | Low |
| Ozonated Water Unit | Variable flow, point-of-use | Simple | Very low |
What Research Shows
Studies on poultry processing found that water with just 1 part per million ozone killed most E. coli and Staphylococcus on chicken carcasses. That’s a tiny amount—barely measurable—but it still gets the job done. While this research looked at processing plants, it proves ozone works against the same germs that trouble live animals.
Keeping Feed Safe with Ozone
Mold in stored feed does two bad things. It wastes nutrients, and it makes toxins that hurt animals. Ozone helps with both.
Ozone for feed mold prevention is gaining traction in the grain industry. Research published in Scientific Reports found that treating corn silage with gaseous ozone at certain levels significantly reduced mold and yeast populations. The feed stayed just as nutritious—starch, crude protein, and total digestible nutrients remained largely unchanged. Some minerals like ash, calcium, and phosphorus actually increased.
For feed that already has toxins, two recent studies show ozone can help clean it up.
A 2025 study from Egypt, published in the Egyptian Journal of Veterinary Sciences, looked at poultry feed contaminated with three common mycotoxins. Researchers treated the feed with UV light plus 10 ppm ozone for 180 minutes. Results showed:
- Aflatoxin B1 reduced by 80.94%
- Ochratoxin A reduced by 84.07%
- Fumonisin B1 reduced by 83.6%
The study also checked feed quality after treatment. Fat quality stayed good based on peroxide value measurements, and other nutrients remained within acceptable ranges for poultry feed.
A separate 2025 study from Iraq, published in the Iraqi Journal of Agricultural Sciences, found similar results—confirming that ozone treatment can significantly reduce mycotoxin levels while keeping feed safe to use.
Mycotoxin control in animal feed matters for all livestock:
- Dairy cows — prevent aflatoxin from passing into milk
- Laying hens — stop toxins from getting into eggs
- Growing pigs — maintain feed conversion and immune health
Bottom line: ozone stops mold before it starts. Research shows it can reduce fungal growth in stored silage and grains. And if mold does get going and produce toxins, ozone can clean up a significant portion of the damage—up to 80% or more for some mycotoxins. Stopping mold first is still better, but it’s good to know ozone gives you options for dealing with contaminated feed.
Odor Control That Actually Works
How Ozone Stops Smells
Most “odor control” products just cover smells with perfume. Ozone actually destroys the molecules causing the smell.
When ozone hits ammonia or hydrogen sulfide, it breaks those molecules apart. The gases that stink get turned into harmless stuff with no smell at all. No covering up. No pretending. Just gone.
Livestock odor control solutions need to address multiple compounds:
- Ammonia (NH₃) – sharp, pungent smell
- Hydrogen sulfide (H₂S) – rotten egg smell
- Volatile organic compounds – various odors
Ozone handles them all.
Real Results from Real Farms
A study in Korea tested ozone water spraying at a livestock manure facility. Before treatment, ammonia measured 8 ppm at the site—well over the 1 ppm limit. After spraying ozonated water, ammonia dropped by about half. Other smelly compounds dropped by 98%.
Computer modeling showed that after ozone treatment, smells stayed inside the property line instead of drifting to neighbors. For farmers getting complaints, that’s the difference between staying in business and facing fines.
For pig farm odor complaints, ozone systems have resolved long-standing disputes in several cases we’ve documented.
Making It Automatic
Modern systems hook up to air sensors. When ammonia starts to rise, the ozone kicks on automatically. You don’t have to guess when to treat. The barn stays fresh all the time with no extra work.
Treating Wastewater with Ozone
Manure wastewater is tough to clean. The ammonia levels run high, and biological treatment takes forever.
Research shows that catalytic ozonation with activated carbon works well for treating livestock wastewater.
A 2025 study published in the Fujian Journal of Agricultural Sciences found that under the right conditions—pH at 10, with 40 grams per liter of powdered activated carbon—99.6% of ammonia nitrogen and 73.6% of total nitrogen were removed after 84 hours of treatment.
Electron paramagnetic resonance testing confirmed that the activated carbon boosted free radical production by more than five times compared to ozone alone. These free radicals kept working for over 60 minutes.
Livestock wastewater treatment with ozone offers:
- Reduced ammonia nitrogen
- Lower COD and BOD
- Clearer effluent
- Less odor during storage
For farmers, this means you can treat high-strength wastewater before storing or spreading it. Cleaner waste means less environmental risk and fewer regulatory headaches.
Putting Ozone to Work on Your Farm
Setting Up the System
Ozone systems fit into existing farm setups with minimal fuss. Air treatment units mount in barns and run during empty periods between groups, or with safety controls during occupancy. Water treatment ties into your plumbing before the drinker lines.
How to use ozone in poultry houses:
- Install X-DOZ unit in central location
- Set timer for treatment during downtime or night hours
- Connect sensors for automatic ammonia control
- Monitor results through improved bird health
For swine facilities:
- Use X-TWO for drinking water treatment
- Add air treatment for odor control
- Consider wastewater treatment for manure storage
XINOZONE offers different setups depending on your main goals:
- X-DOZ model for air and surface treatment—best for odor control and general disinfection
- X-TWO venturi system for main water lines
- Dedicated ozonated water units for simpler water treatment
Cost of Ozone Systems for Livestock
One of the most common questions we hear: How much does an ozone system cost?
While every farm is different, here are general ranges:
| System Type | Farm Size | Typical Cost Range | ROI Period |
| Air treatment only | Small (up to 10,000 birds) | $3,000 – $5,000 | 6-12 months |
| Air treatment only | Medium (10,000-50,000 birds) | $5,000 – $12,000 | 8-15 months |
| Air + Water treatment | Medium farm | $8,000 – $18,000 | 10-18 months |
| Complete system (air+water+waste) | Large operation | $15,000 – $35,000 | 12-24 months |
NOTE: The above cost range is an industry estimate, and the actual price varies depending on the configuration and region. Please contact us for an accurate quotation.
Factors affecting ozone generator price:
- Barn size and volume
- Number of barns
- Water flow rate
- Automation level
- Installation complexity
Most farmers find the combination of benefits pays back the investment faster than they expected. When one piece of equipment solves five different problems, the math works out.
Safety First
Ozone is powerful stuff, and like any tool, you need to treat it with respect. Systems should keep ozone levels safe for animals and workers during operation. That usually means treating when barns are empty, or using dissolved ozone in water where off-gassing is controlled.
Modern systems include monitors and automatic shutoffs. Follow the manufacturer’s setup guide and you’ll be fine.

Common Questions About Ozone on Farms
General Questions
Is ozone safe for my animals?
Yes, when used correctly. Air treatment happens when barns are empty or with careful monitoring. Water treatment uses dissolved ozone at levels that kill germs but don’t hurt animals. The FDA and USDA have approved ozone for food contact and water treatment.
Will it work in my type of barn?
Ozone systems work in all kinds of livestock housing—poultry houses, pig barns, dairy free-stalls, and calf hutches. The key is matching the system size to your barn volume and water use. We’ve installed systems in:
- Broiler houses (20,000-50,000 birds)
- Layer operations
- Swine farrowing and finishing barns
- Dairy free-stall barns
- Calf hutches and nurseries
Can I run it while animals are inside?
Air treatment during occupancy requires careful control and monitoring. Many farmers treat at night when animals rest and ventilation runs lower. Water treatment runs continuously with no issues.
How long before I notice results?
Odor improvement is often noticeable within days. Health benefits like lower mortality and fewer respiratory treatments show up over the first few batches after installing.
Installation & Maintenance
How much maintenance do these systems need?
Very little. Keep the equipment clean and check connections now and then. Most farmers spend maybe an hour a month on maintenance.
Can I install it myself or need a professional?
Basic systems come with installation guides and can be installed by farm staff. Complex setups with multiple barns may benefit from professional installation. We offer remote support for all customers.
What kind of power does it need?
Standard 110V or 220V, depending on system size. Our team will help you determine requirements.
How long do ozone generators last?
With proper maintenance, 10-15 years. The ozone generation cells may need replacement every 3-5 years, depending on usage.
Cost & ROI
What’s the ROI period for a poultry farm?
Most poultry operations see payback in 8-18 months through:
- Lower mortality (1-3% improvement)
- Better feed conversion (2-5% improvement)
- Reduced medication costs
- Fewer flock rejects
What’s the ROI for a pig farm?
Swine operations typically see payback in 10-20 months through:
- Reduced respiratory treatments
- Better daily gain
- Lower mortality in nursery pigs
- Fewer odor complaints
Technical Questions
What size system do I need for my farm?
It depends on barn volume and water usage. Send us your barn dimensions and animal counts, and we’ll calculate the right size.
Can I treat both air and water with one system?
Some larger systems can handle both, but most farms use dedicated units for each application for optimal performance.
Does ozone affect beneficial bacteria?
In water, ozone kills all bacteria—but beneficial bacteria in the gut come from feed, not water. In air treatment during empty periods, there are no beneficial bacteria to affect.
Will ozone damage equipment?
At proper concentrations, no. Stainless steel and most plastics are ozone-resistant. We’ll advise on any materials to avoid.
